Initially part of [[British Rail]] [[Network SouthEast]], the line was [[Privatisation of British Rail|privatised]] in 1994, the track being owned by [[Railtrack]] (subsequently [[Network Rail]]) with the passenger service provided by the North London Railways franchise. This passed to [[National Express]] in 1997, which operated the line under the brand name [[Silverlink]] until November 2007. Under Silverlink, the [[slam door trains]] were replaced by [[British Rail Class 150|Class 150]] units in 2000, which improved reliability significantly. There were minor improvements in station facilities (such as CCTV and information points) but no major investment to upgrade the line and boost capacity, and the stations remained unstaffed.
